iM 2 Mesh Platform

Overview
Jasmines iM2Mesh platform is here to
overcome the fundamental problems of
broadcasting, bandwidth, authentication and
security, normally seen in a traditional
single radio point to multipoint wireless
installations.
Heart of the iM2Mesh is a Multi-radio
modular Wi-Fi node (a.k.a. iM2Mesh Node).
Single-radio access points (or even dualradio
access points, in which one radio is
used for client devices and the other for
mesh backhaul) pose performance problems
and hinder scalability. Jasmines iM2Mesh
Node solves these problems for large-scale
network deployments.
Jasmine iM2Mesh platform is a turn-key
methodology of network design for multiradio
multi-hop wireless mesh networking.
The goal of Jasmine iM2Mesh network is to
provide turnkey solution for building a
scalable multi-hop wireless mesh network.
Jasmine iM2Mesh network can be deployed
as a last mile solution for Internet access in
rural connectivity, residential and
commercial areas. Jasmine iM2Mesh network
is addressing key issues regarding efficient
and scalable routing with load balancing;
provide maximum bandwidth delivery up to
the last point of the network, built-in
capabilities of authentication and security of
user data during wireless communication.
Wireless networks which requires voice,
video and data services, can use different
service radio for different services. This type
of setup provides dedicated link for backhaul
traffic and client coverage.
Building Blocks
Building blocks of iM2Mesh network consist
of hardware and software to deploy end to
end intelligent, secure and powerful wireless
delivery network which can support large
client base.
iM2Mesh Node: iM2Mesh Nodes are the
backbone of the iM2Mesh network.
Wi-Fi Receivers: Wi-Fi Receivers are
CPE devices for fixed wireless users and
want to access Wi-Fi network from distance.
iM2Mesh Authentication Server:
Authentication server is a surfing cop
managing users, delivering custom welcome
page, managing bandwidth for each
individual users.
Features
iM2Mesh network is a turn-key solution from
Jasmine wireless to deploy large rural
connectivity network or city-wide Wi-Fi or
wireless network for fixed and mobile
wireless and wired clients.
Scalable: iM2Mesh network is scalable;
there is no multi-hop limitation as each
iM2Mesh Node operates with multiple-radios
and with multiple-channels. iM2Mesh Node
supports standard mesh protocols such as
OSPF and OLSRD.
Modular: iM2Mesh Nodes, a vital part of
the iM2Mesh network can support radios
with different standard like 802.11b,
802.11g, 802.11a or even Wi-Max.
Secure: Each iM2Mesh Node supports up
to 4 Radios, which can run built-in captive
portal services to authenticate mobile users
as well as users connecting through Wi-Fi
Receivers.
Manageable: Each iM2Mesh Node is a
manageable node for iM2Mesh
Authentication server, which is central part
of network administration. Its GUI based
interface provides number of users
connected and how much bandwidth each
interface is using, without installing any kind
of management or SNMP based system.
Upgradeable: iM2Mesh Nodes radio
agnostic architecture supports multiple
standard based radios, makes is possible to
upgrade on the field without replacing
complete hardware.
Standard Based: Standard based
platform to support, laptop users with
different standards wireless cards.
Quick T2I (Time to Install):
iM2Mesh platform based network is a turn
key solution for providing wireless
connectivity to residential as well as
industrial areas, as each component is
tightly integrated with each other makes
deployment easier than ever.
iM2Mesh platform is a best suited platform
for wireless operators and can be deployed
as a last mile solution for Internet access in
residential and commercial areas.
Technology
iM2Mesh, Operates just like wired network.
iM2Mesh network uses iM2Mesh Nodes in a
backbone which runs dynamic routing
protocol, which can emulates separate
network for each interface, just like
corporate networks uses routers or switches
to scale network. Just like Wired networks,
iM2Mesh based Wi-Fi networks are:
Scalable: Just like wired network iM2Mesh
network uses same techniques to split every
network in uplink and downlink network with
each section of network operates on
different IP and broadcast domain, providing
very scalable and manageable network.
Each network also operates on separate Wi-
Fi channels providing more channel usage
resulting more bandwidth utilization for
overall network.
Stable: Because each part of iM2Mesh
network is operating independently, makes
whole setup lot more stable than wireless
networks operating using ad-hoc mode.
Each iM2Mesh Node in a network including
clients and Wi-Fi receivers uses
infrastructure mode for wireless
communication which is far batter stable
and manageable than ad-hoc mode based
Wi-Fi mesh networks.
Preserves Bandwidth over
multiple hops: Just like wired routed
network, in iM2Mesh bandwidth delivery is
same from start to end, resulting network is
not limited by hops
Supports radio agnostic network:
Adding or replacing radios in iM2Mesh Node
is a matter of minutes. iM2Mesh Nodes can
operate with different type of radios i.e.
802.11b, 802.11g, 802.11a or Wi-Max.
Dynamic routing and network setup are
independent of radio underneath, so at
layer-2 any supported radio interface can be
operational.
Supports multiple backhaul
radios and multiple service
radios: iM2Mesh Node can also
support multiple service interface
and multiple backhaul radios, it can
be configured based on ISP's
requirements of the network. Each
radio can operate on separate
channel forming scalable routed
network provide Wi-Fi connectivity to
large networks. It also supports
completely dynamic configuration as shown.
Deployment Scenarios
iM2Mesh network is a turn-key solution with
wireless intelligence at the EDGE which
can be deployed based on network design
requirements of the ISP. Each building block
of iM2Mesh is tightly integrated to each
other, so careful planning should be done.
Points to be considered before deploying
iM2Mesh platform
Bridging v/s Routing: When you
connect two networks, you have two basic
choices: bridges or routers. If the networks
are small, and the connection is not low
speed, then a bridge makes sense because
it just passes every bit of traffic to both
sides: the bridge really joins the two
networks together transparently.
But that strength is a weakness if the
networks are large or the link between them
is slow. A router will only pass packets that
actually need to be passed. So routing is
batter than bridging when you have large
network, routers dont allow broadcast
based windows browsing, which is what we
need, no computers in Wi-Fi networks to be
seen by each other.
